Given Input Data is 666, 168, 838, 121

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 838 is 2 x 419

Prime Factorization of 121 is 11 x 11

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(666, 168) = 18648

GCD(666, 168) = ( 666 x 168 ) / 18648

GCD(666, 168) = 111888 / 18648

GCD(666, 168) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 838

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(6, 838) = 2514

GCD(6, 838) = ( 6 x 838 ) / 2514

GCD(6, 838) = 5028 / 2514

GCD(6, 838) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 121

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(2, 121) = 242

GCD(2, 121) = ( 2 x 121 ) / 242

GCD(2, 121) = 242 / 242

GCD(2, 121) = 1

GCD of 666, 168, 838, 121 is 1
